Diagnosis

Female micropterous; head and thorax yellowish brown, abdomen dark brown, all legs fully yellow; antennomere I concolorous with head, II yellow, III yellow with apex yellowish brown,  IV–VIII brown with paler bases, gradually darker until VIII. Antennae 8-segmented, basal antennomeres without stout and capitate setae; III and IV with 3 sense cones each. Head strongly reticulated, about 1.25 times as long as the greatest width; only the postocular setae is well-developed and capitate, with a similar length to the eye; lateral margins curved and constricted behind globose eyes; maxillary stylets wide apart. Pronotum reticulated, with 4 pairs of well-developed and capitate setae, anteromarginal pair reduced or absent; prosternal basantra present. Meso- and metanotum strongly reticulated. Pterothorax without a pair of stout and capitate ventrolateral setae on each segment. Pelta broad, with a half circle shape, reticulated; abdomen sculptured, tergites II–VII apparently without wing-retaining setae. Tube cone-shaped, weakly reticulated only at base and without lateral setae, about 1,7x as long as basal width. All legs similar in appearance, tibiae without tubercles, fore tarsi with a tooth. Fore wings without duplicated cilia.

Male micropterous. Similar to female, except for having  setae S2 of abdominal tergite IX shorter. Pore plate present on abdominal sternite VIII, shaped like a small circle medially.

Intraspecific variation

Unknown.

Genus and similar species information

Glyptothrips is a genus with 14 valid species, with an apparently disjunct distribution between North and South America. The members of this genus have a strongly sculptured body, but tube usually smooth; head incut behind small, globose but well-developed eyes; postocular and main pronotal setae (except anteromarginal pair) well-developed and with capitate apex; and most species bear strong and capitate setae on basal antennomeres and/or ventrolateral region of pterothorax. Glyptothrips bucca is distinguished from the other brazilian species in the genus for lacking stout and capitate setae on the basal antennomeres, for antennomere IV bearing only 3 sense cones, and for the small and circular pore plate in males. A key to the Brazilian Glyptothrips species is available in Lindner et al. (2023).
